The NCP3337 is a high performance, low dropout regulator. With accuracy of ±0.9% over line and load and ultra−low quiescent current and noise it encompasses all of the necessary features required by today’s consumer electronics. This unique device is guaranteed to be stable without a minimum load current requirement and stable with any type of capacitor as small as 1.0 F. The NCP3337 also comes equipped with sense and noise reduction pins to increase the overall utility of the device. The NCP3337 offers reverse bias protection.
